Wearable technology is the big thing at CES 2014 in Las Vegas this year and Sony is eager to jump on the band wagon with the launch of the SmartBand, a fitness tracker which promises to be the first in range of products in Sony's SmartWear line.

Earlier on Monday we say LG launch it's first fitness tracker then Lifeband Touch, which aims to combine an activity monitor with some smartwatch features.

The SmartBand works in basically the same way as any other fitness tracker by tracking your daily activity and then displaying this visually in a new app from Sony called Lifelog.

Sony says that its wearable technology is about more than "just the steps you take" but is about "emotion as well as motion."
